Tlpaiienieii lilla-r. This application filed November 1913. Serial No. 803,5?4.

Be it known that l, llamo.' 'ilrrnofan a citizen of the United ritmes, renidingr at Chicago, in the County ol (ook and Slain of lliinois, have .invented useful improvemenls in tion.

My invention consists olf an improved device for preventing the longitudinal weeping of the rails of a railway trarhr relative to .the ties.

rlhis application is in part a division of my former application, Serial No. 7 78,1380, filed July l, i913, for anti-rail Creepers .which resulted in .Patent 1,083,603, dated aan. 6,1914-,

The objeoe and advanta'es oi my imw proved device are fully i'orth in the following description and claims and illustrated in ihe drawings. v

Among the objects of my invention are the simplification of a device of this kind, a redaction in the number of parts, and in the amount of material necessary in Constructing the same, without sacrifice oi eliicienoy.

A. further object is the improvement in the operation oi? tbe device by securing a 'greater irictional Contact between tbe tionary anti-Creeper device and the rail to which it is applied.

It will be apparent vfrom the following description. and drawings, that this anti-rail Creeper exerts a transl-verse pressure on the edgee oi" ille rail base aswell as n frietional eoiitao; between ihe lower side of the rail base and the upper. surface oi' one member of my anti-Creeper structure.

Referring to jthe drawings-Figure l shown a, cross section oit' a rail with my iinprovetl anti-ereeper assembled and applied thereto. Fig. 2 is a plan view of lhe Same. Fig. 3 is 'an elevational view of the main member oi my improved anti-ereeper. Fig. 3 is an elevational View oi a slight modifi* cation of the member Shown in Fig'. 3. Fig'.

Fig. 5 ie an end View or' the main .member Shown in Fig. 3. in. 6 is a plan view oi the second or wedge nieinber o1 mv nprored. antieereeper. Figs. i end @i a of the opposite endmoiE Wod' shown in 6. lli? and Figi. l() is a poi peetivo view oif' the wedge nuanber. Referring to die drawings, it will be seen i'hat my invenion Consists nuhetanliallf. ol two elements, a main meinher designated l and a second. or wedge` member deeionatml i3.

The main nnrinber l ie formed at one end with au uplurned lip or jan l which is inturrned. as; shown at 2, to embrace the edge and part oi the npr er surface oi. the rail base. The main member A is adapted to eX- tend beneath and in contact with the lower surface of the baee of. the rail 3 and pro jerte beyond the opposite of the rail base. Ai the end opposite the jaw l 2, the member j, is providmi with an lip-Standing ehonlder il, the inner, enbelantially vertical iaco, i o1 which converges toward the edge of the rail base in lhe diret-tion of the adjacent lie i', against. whioh the downwardly exteinlingabutment 8 on the main member is adapied to bear.

The under sido of the end of the member A. opposite the lip or Jaw l 2, is pr(J vided with a #urtare l i. which ivuines downw '.rdly toward the adjaf'ez'it le 7. l, prefei :bly provide the men'iber A with ribA l2. n'hivh may be terminated in saoul; ders 123 adjarent the inner boundary of the surface ll.

The gerend or Wedge member B has in a general way the form of a box open alo-ng one .eide and at one end. The opening or :slot .i7 along' i'he side oi' the wedge member has its lower face 'li' inrlined to correspond to the inclination ll, on the lower side of the wedge end of the main member A. From the upper Wall of the opening' or slot 17 along the side of the Wedge member, there depends a rib 18 having' along its inner face an inclined sur'laee 5 cmresponling in inclination to the inclined surface 5 upon the main member A. The wedge member is preferably closed at the end 19, thisl 0nd b0- ing shown in Fig. 7, but at the opposite end the slot or opening` i7 extends completely throughv the end 2O of the Wedge member,

strengthenir 'the end 2() being shown in Fig'. 8 of the l ber Ais placed under the raii with its iip of, shown in Fig. 3, with the surface 5 coacting with the surface 5 and the surface 1l coacting with the surface l1. A The 'coaction between the surfaces 5 and 5 causes the'raii base to be gripped transversely between the Wedge member B and the upstanding lip or jaw l-2 at the opposite end ofthe first member. The coaction between the surfaces lil and 11, when the wedge memberB is impelied toward the tie, has the eect of vforcing or drawing the main member A upward toward the rail by reason of the fact that the lip 23- of the Wedge Imember over- `iies the edge of the rail base While the surface l1 inclined doivnwardiytoivard the tie forces the main member A upward, as the Wedge member moves toward the tie.

In practice the members A and B are castings having unnished Wedging surfaces so that the initial assembiage, as the abut ment 8 upon the main member bears against a tie, toward Which the traffic is moving, the movement of the Wedge member B When forced toward the tie may, owing to the roughness or irregularity of the said coacting surfaces, cause the wedging surface 5 to seat and bind on the Wedging surface 5 before the other Wedging surface il on the Wedge member has seated en the surface 1l on the main member, or before it has forced the main member into binding Contact with tne under surface of the rail. I At this period in the adjustment of the anti-creeper, a transverse pressure only will be exerted on the lateral edges of the rail base. When the Wedge member is driven further toward the tie it will have tbe e'ect of stretching or extending the main member Ain the direction of the arrow 25 in Fig. l by virtue of the elasticity of the material of which it is constructed until the Wedgingisurface ll has seated on the surface 1l, at which stage in the adjustment, a vertically acting pressure will be set up between the member A and the rail, the creeping of the rail thus being retarded by the frictional resistance on the bottom thereof as Well as by the horizontal gripping of the edges of the base.

On tbs other band, shouid the Wedging suru face 1i seat rst, the wedge member Whe apart sf said Wedge member.

the direction of the arrows Q4 in Fig'. 8 bv further toward the tie wii cene." '1^ virtue of the elasticity of the material, ivniciAv further movement of the wedge member B toward the tie causes the Wedging surface to seat on the surface 5 on the main member A, thereby causing a transverse gripping' of the base of the raii.

Referring to Figs. 5a and et I preferably provide the ribs 12 of a lesser depth from a point adjacent the end thereof ha ing tire overhanging jaw or lip 1-Q to the inclined under surface ila as shown at l`-, T" serves to weaken the member ac entI the said jaw so that any bendingi take place in the' member A by i pressure exerted thereon will ceci jaw, thus leaving the centrai member with a fiat upper si affording the largestpossibie frictionai sistance to the creeping of tbe i erabiy also recess the upper surrace of tne member A, shown U3, in order te ailow ample clearance for the edge of rail base under the lip or javi l-2. The abutment 8 may be located approXiniat-eiy at the center of the rail., as shown and Ph This modified main member is aise provided on its under side negar tbe center of the end opposite the jaw ii depending ing' l5 forming a adjacent the'inner boundary o under surface 11", against iv wail of the wedge member bear, thereby preventing any ro ment of the iatternieinb substantially parailei to From the foregoing apparent tuat prov'de a cl rail anchor, capabie beine' to the rail and creeping' of the rail.

I 'have' described in detail a particuiar Vform of my invention, but the invention is not limited to this particular form, inasmuch as the principle thereof may be embodied in structures of Wideiy divergent form. F or instance, it Wiii be obvious that by reversing` the inclination of the wedging surfaees the device might be used with tbe Wedge member abutting against the tie instead of bavi??? infr the main member abut against the tie.
